To ALL WHOM IT MAY CONCERN;

Be it known that I, AI-IltRlsEn'r DAVIS, of Troy, in the county of Rensselaer, and State of New York, have invented n new end improved Pile for `fnztlring Steel-Headed Rnilfor Railroads; and I do hereby declare that the following-is a. full, clear, and exact description thereof, which will enable others skilled in the srt to make and use the some, reference being had to. the cccompanyingdrewings, forming port of this specification, in which- Figure 1 is an end View of my improved pile.

Figure 2, on end view of a. rail rolled from the same.

Similar letters of reference indicate like parts.

This 'invention relates to a. new und useful improvement in the manufacture of steel-headed rails, or those which are composed of ou iron neck and base and a steel heed or upper surface. The invention consists in a. novel manner of forming the 'pile from-which the rail is rolled, whereby the steel head or upper surface is firmly connected to the lower iron portion and efectually prevented from separating underthe wear and tear to which' the rail is subjected by the action, of the cor-wheels upon it. Y

The pile is vcomposed of o seriesr of hairs, A AV, oi"v iron, of proper dimensions und of 4re'ctzingulm form, laidone upon the other, as shown clearly in fig. 1, and when different qualities of viron .are used the bars A' of the better quality are arranged in the pile, as shown clearly in iig. 1, so as to form, when the rail is'rolled, an outer costing of' superior inetal. The upper bars A of the pile are formed with longitudinal grooves, a, und

angular projectionspb, extending theirivhole length, and B is a. steel cap rolled with lipor pendent flange, c,

ut each side, and with angular pendent projections, cl, and grooves e at'its under side, tho iianges c extending down over the sides of the'upper borsA, and the projections bof the upper bars fitting in the grooves e of the steel cap, and the projections d of the steel cap fitting in-the grooves a of .the upperiron bars A. The pile thus formed is properly heated and rolled into a. vrail by passing it between the usual rollers, -und the steel cap B` is spread over the entire upper surface of the rail, and extends down at each side of the same nearly to the neel: y", as shown clearly in fig. 2. The angular projections end grooves at the under` sido of the steel cop, undl the grooves und projections at the upper sides of the ,upperfburs A being fitted together :is shown, `ci'ecturilly prevent the separation of the Asteel head freni the lower iron portion, as n weld or a, union by pressure is not alone depended upon for adhesion. The union'of the two" different qualities of iron is also on important feature' ot' the invention, us a, few bars, A', of superior iron, arranged or disposed with the bars A', of inferior quality, :is shown, will form a. strong, durable,` and economical rail.

Hoving thus described my invention, I claim :is new, and desire to secure by Letters Patent-f The rolling or making ofroils. for railroads of o pile composed of a, series of iron bars, A, provided with .n steel cup, B, formed or rolled with a. pendent iiunge at each side, and with longitudinal grooves and projcctions, en b, :it its under surface, and the upper iron bars ofthepile rolled or formed with corresponding grooves and proections, a d, to admit of the steel cap and upper iron bars being locked together, substantially as shown nnd'ilescribed. Y 1

1 further clsim'forrning the iron ,portion of' the `piloot' bars A A ofsupe'rior andinferior iron, arranged or disposed substantially in the manner as and for the purpose'isct forth.
